Sněžka is boring as hell.
Gamecon is pretty fun, one of the best in ČR, you should consider to come anyway :) Actually, the main organizer asked me about you personally and told me that I should invite you - does the main organizer of the con in Poland want you to come so much as Erric does? :)
eAnd also: Every autumn, usualy in September, we go to Dalava, it´s one cottage in South Czech, need to Český Krumlov. We will be happy to see you there :)
